== Daughterboard Specifications==
===E310 MIMO XCVR board===
The USRP E310 MIMO XCVR daughterboard features an integrated MIMO capable RF frontend.

===Tuning===
The RF frontend has individually tunable receive and transmit chains. Both transmit and receive can be used in a MIMO configuration. For the MIMO case, both receive frontends share the RX LO, and both transmit frontends share the TX LO. Each LO is tunable between 50 MHz and 6 GHz.

===Gains===
All frontends have individual analog gain controls. The receive frontends have 76 dB of available gain; and the transmit frontends have 89.5 dB of available gain. Gain settings are application specific, but it is recommended that users consider using at least half of the available gain to get reasonable dynamic range.

===LO lock status===
The frontends provide a lo-locked sensor that can be queried through the UHD API.

<syntaxhighlight lang="c++">
// assumes 'usrp' is a valid uhd::usrp::multi_usrp::sptr instance
// get status for rx frontend
usrp->get_rx_sensor("lo-locked");
// get status for tx frontend
usrp->get_tx_sensor("lo-locked");
</syntaxhighlight>

===Filter and Antenna Switches===
The transmit and receive filter banks uses switches to select between the available filters. These paths are also dependent on the antenna switch settings. Incorrectly setting the switches generally results in attenuated input / output power. Receive filters are band pass (series high & low pass filters), transmit filters are low pass.

Source code related to controlling the filter band and antenna switches resides in <code>e300_impl.c</code>. Specifically, refer to methods <code>e300_impl::_update_bandsel</code>, <code>e300_impl::_update_atrs</code>, <code>e300_impl::_update_gpio</code>, and <code>e300_impl::_update_enables</code>. Generally, these methods set the switches depending on the state of transmit and receive streams.

The following sections provide switch setting tables for antenna and filter selection for frontends A & B receive and transmit paths. For futher details refer to the schematics.

===Side A Filter and Antenna Switches===
''Note: X = don't care, T = If full duplex, set bits according to transmit table, otherwise don't care. Filter range A – B will be selected if A <= freq < B.''

==SD Card Images==

* [http://files.ettus.com/e3xx_images/ http://files.ettus.com/e3xx_images/]

This folder linked above contains SD card images and the SDK (OE cross-compiler build environment) for the USRP E310 and E312. There is a manifest file that shows which packages, and which versions, are included in the OE build within each folder.

The "<code>alpha</code>", "<code>beta</code>", "<code>e3xx-release-001</code>", "<code>e310-release-002</code>", "<code>e3xx-release-3</code>" folders contain older versions which are currently obsolete. We do not suggest that customers use these files. These versions are no longer supported. They are provided here for archival purposes only.

The current version is Release 4, which located in the "<code>e3xx-release-4</code>" folder. We recommend the customers use this version. It is fine if you are already successfully using an older version, but at some point it is recommended that you upgrade to this current version so that you benefit from the latest bug fixes, new features, stability improvements, and other enhancements.

The Release 4 image includes UHD 3.9.2 and GNU Radio 3.7.9, and also includes the corresponding FPGA image file.

'''Note:''' An 8 GB SD card is required for the Release 4 image.

The SD card image contains both the FPGA image and the OS for the E310/E312. The FPGA images are located in the file system of the E310/E312 in the <code>/usr/local/share/uhd/images</code> folder.

There are two SD card image files for each version of the image, which include the text "<code>-dev</code>" and "<code>-demo</code>" in the filename. The "<code>-dev</code>" flavor lacks some graphical packages, such as X Windows and QT, which the "<code>-demo</code>" flavor includes. The two flavors are otherwise functionally equivalent, although the "<code>-demo</code>" flavor takes some additional space on the SD card and some additional memory to run.

The Release 4 image comes in two varieties. The variety that you will need depends on the product number of your E310 or E312, which is printed on the bottom of the device.

For the E310, the product number will be <code>156333X-01L</code>, where X is a letter from A to Z. For devices where X is A, B, C, D, the images under the "<code>ettus-e3xx-sg1</code>" folder should be used. For devices where X is E or later, the images under the "<code>ettus-e3xx-sg3</code>" folder should be used. You must use the appropriate image for your specific device. The incorrect image will not work, and will only boot as far as the U-Boot boot loader before stopping.

For the E312, the product number will be <code>140605X-01L</code>, where X is a letter from A to Z. The images under the "<code>ettus-e3xx-sg3</code>" folder should be used for all E312 devices.

You can burn the image to an SD card using either the "<code>dd</code>" or the "<code>bmaptool</code>" tool. Instructions on how to use these tools are at the links below.

* https://gnuradio.org/redmine/projects/gnuradio/wiki/Copy_an_image_file_to_the_SD_card

The SD image files have an *.xz extension, as they are compressed using the LZMA/LZMA2 compression algorithms. You can uncompress these files with tools such as 7-Zip and the XZ Utils. Please see the links below for further information.

==USRP Embedded Series FAQ==

===General USRP E31x Questions===
'''Q:  What data rate is supported for continuous sample streaming to a desktop or laptop host-PC?'''
A:  Unlike host-based SDRs such as the USRP B, N, and X Series devices, the USRP E Series devices are not intended for continuous streaming of high bandwidth data to a desktop or laptop host-PC. The SDR application runs on an embedded CPU with limited processing capability. Users should leverage the FPGA using tools such as RFNoC to offload compute intensive algorithms that process high bandwidth samples.

'''Q:  What data rate is supported between FPGA to the ARM processor?'''
A: Due to the limited performance of the embedded processor, the maximum data rate from the FPGA to ARM cores is approximately 10 MS/s, and will vary with the processing load on the CPU. The AD9631 RFIC is capable of capturing 56 MHz of bandwidth. Processing signals at full bandwidth requires implementing algorithms on the FPGA.

'''Q:  What is the purpose of the 1 GbE port?'''
A: The E Series can run a DHCP client on the 1 GigE interface to enable connection to a larger network for remote access by another computer. Power over Ethernet is also supported on the E313.

===USRP E313 Questions===
'''Q: Which environmental tests were performed?'''
A: The USRP E313 is tested against multiple environmental standards to ensure operation in outdoor conditions. These test include ingress protection, temperature, humidity, mechanical shock, random vibration, and altitude. Detailed specifications are provided in the [link data sheet]. 


'''Q: How do I protect external devices connected to the host USB port?'''  
{|
|style="vertical-align:top"|
A: A circular conduit interface is provided in the kit. This component has large and small threaded ends. The small end connects to the USB port on the USRP E313. The user will need to connect their own waterproof structure to the large end to protect the USB device. Since requirements for external devices vary greatly, the conduit interface serves as a flexible starting point for users to build their own solution. See the [[Media:USRP E313 Dimension Pole Mount.pdf]] of the conduit interface for details.

'''Q: How do I protect unused ports?'''
A: All ports come with protective end caps that should be left in place on unused ports.

'''Q: Why is a DC power supply not included?'''
A: The RJ45 port supports Power over Ethernet and is intended as the primary power supply option. However, users can still use a DC power supply. Since requirements for supplying DC power in outdoor scenarios can vary greatly, a waterproof sleeve for the DC port is provided as a starting point for users to design their own solution. A waterproof sleeve for the RJ45 port is also provided.

'''Q: Do the RF inputs have lightning protection?'''
A: The DC and PoE power inputs have surge and lightning protection, but the N-type RX/TX inputs and SMA GPS input do not. Users should design antenna lightning protection based on their application requirements.
